Some wiki updates - Would like some feedback

[JWH_Matthew]

Hello everyone,

I just found about GetSimple some days ago. I found the Wiki really helpful and decided to update its content as I was learning from it.

I though the tabular format for the main page to be a nice enhancement to make it clearer and would like some feedback on it.

I really like collaborating to it and will surely do it again in the future.

I personally like the changes. Thank you for the contribution.
